Allen-Bradley 100-B250N3 Contactor Coil Assembly

Allen-Bradley 100-B250N3 IEC Contactor, Series B, is a three-pole motor starter rated for 250 A, designed for rugged industrial automation applications. It uses a 120 V AC coil to energize the contactor, allowing PLCs or local control circuits to switch three-phase power to motors. As part of the Series B family, this IEC-contactor provides three line-side contacts in a compact, dependable package suitable for motor control centers and other industrial control panels where robust 3‑phase switching is required. The 100-B250N3 designation identifies a 3-pole configuration with a 120 V AC coil, making it compatible with common control voltages in many facilities.
